You will need:
Guitar Hero controller
Size 10 Torx screwdriver
Small philips screwdriver
Large-ish flat screwdriver
Duct tape (I used black "Duck" tape)
"Blu-tack", or other poster adhesive putty (e.g. "white-tack")
This idea is not mine as people have done similar things before, but there is no instructable, or indeed any clear set of instructions that I could find. And I haven't found any examples of people doing it to a Guitar Hero 3 controller, although the principle is the same for other GH guitar versions.
This is my first instructable so please be kind :)
Step 1: Remove all screws in the guitar neck
You will need a size 10 Torx screwdriver for this.
